Will Smith’s next movie — part cop flick, part sci-fi — has all the makings of a Hollywood blockbuster except one. When “Bright” is released later this year it’ll be playing on Netflix Inc.’s streaming service, not thousands of theater screens. Once an industry outsider, Netflix has emerged as one of the TV industry’s most powerful forces with shows including “House of Cards’’ and “Stranger Things,’’ earning awards and attracting millions of viewers. Though the Los Gatos, California-based company has released dozens of films in recent years, it hasn’t had the same impact in movies. Now, the world’s largest paid video service is devoting more attention to motion pictures, looking to shake up that business just as it has TV.
